The utility model rotates chuck drive shackle rod through manual rotation and moves; The anchor clamps dop and the jacket body generation of its taper are relatively moved, reach the purpose of clamping work pieces, it is easy and simple to handle, rational in infrastructure; The clamping force of clamping workpiece is big; Positioning accuracy is high, satisfies the requirement of various processing works to clamping force, has improved working (machining) efficiency and crudy.
Description of drawings
Specify the utility model below in conjunction with the accompanying drawing and the specific embodiment;
Fig. 1 is the structural representation of the utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with the specific embodiment, further set forth the utility model.
Referring to Fig. 1, present embodiment provide a kind of easy to use, chucking power is big, the hand actuable clamping device that is used for the clamping workpiece that positioning accuracy is high comprises fixed frame 10, jacket body 20, anchor clamps dop, shackle rod 40 and rotates chuck 50.Jacket body 20 is installed on fixed frame 10 and is rotated chuck 50, be processed with internal thread in this rotation chuck 50, shackle rod 40 1 ends are connected with the anchor clamps dop, drive moving of anchor clamps dop; Its other end processes external screw thread; And with rotate that to be processed with internal thread in the chuck 50 suitable; Rotate chuck 50 through manual rotation and drive moving of shackle rods 40, and then drive the anchor clamps dop, the relative motion realization through anchor clamps dop and jacket body is to the clamping of workpiece or get loose.
In the present embodiment, the anchor clamps dop comprises clamp body 31 and is movably connected in a plurality of claws 32 on the clamp body 31, is used for the clamping workpiece.Each claw 32 amalgamation is coniform together, and its center is provided with the clamping chamber 33 of clamping workpiece, is convenient to place work piece.On jacket body 20, be processed with the female cone hole and the axis hole of sectional fixture dop, the combination back is suitable with the female cone hole each other for this claw 32, promptly is conical.Sectional fixture body 31 in axis hole, clamp body 31 is cylindrical, and the one of which end is installed a plurality of claws 32; One end of the other end and shackle rod 40 is connected; Drive clamp body 31 by shackle rod 40 and in axis hole, move, move, make it under the effect in female cone hole thereby drive claw 32; The anchor clamps dop radius of circle that changes after claw 32 makes up is the size in clamping chamber 33, realizes that the anchor clamps dop clamps or the purpose of the workpiece that gets loose.
What deserves to be mentioned is, be fixed with handle 60 at rotation chuck 50, this handle 60 is T-shape and is fixed on the rotation chuck 50, is convenient to manually rotation and rotates chuck 50.On shackle rod 40, also be with connecting rod fixed cover 41 and stage clip 42, this shackle rod 40 is installed on the fixed frame 10 through connecting rod fixed cover 41, and stage clip 42 is arranged between the clamp body 31 of connecting rod fixed cover 41 and anchor clamps dop, realizes the effect of buffering and power-assisted.
In addition; Other end end at shackle rod 41 is provided with stop nut 43; This stop nut 43 is two relatively nuts of tightening of rotation, is fixed on the end of shackle rod 40, avoids shackle rod 40 ends to break away from rotating chuck 50 or inserts in rotating chuck 50.
The utility model is placed on workpiece in the clamping chamber 33 that forms in the claw 32 in use, and pulling handle 60 makes its drive rotation chuck 50 rotate to a direction then; Under the effect of being threaded, drive shackle rod 40 and move, thereby drive the anchor clamps dop to jacket body 20 inner moving; Under the effect in the female cone hole of jacket body 20, each claw 32 is inwardly assembled, and dwindles clamping chamber 33; When handle 60 can't rotate rotation chuck 50, this moment, workpiece clamped, and can carry out the processing to workpiece.
After the workpiece completion of processing, only need reverse rotation to rotate chuck 50, make shackle rod 40 promote anchor clamps dop side shifting outside jacket body 20, claw 32 gets loose, and takes out workpiece and gets final product.
The utility model rotates chuck 50 drive shackle rods 40 through manual rotation and moves, and the anchor clamps dop of its taper and jacket body 20 generations are relatively moved, and reaches the purpose of clamping work pieces; It is easy and simple to handle, rational in infrastructure; Rotating clamping workpiece under chuck 50 rotations, the clamping force of its clamping is big, and positioning accuracy is high; Satisfy of the requirement of various processing works, improved working (machining) efficiency and crudy clamping force.
